Reply to "LUBRICANT SELECTION"

Jayesh,

One way to identify better product, for general maintenence lubricants,is by specification. In the case of Engine oils for Petrol/Gasoline applications; benchmark against API performance specs. From the now obselete, API SA grade, SF is better and SG better (than SF) and SH better than SG.

Similiarly for other applications, like Hydraulic oils, AW type is better than an R&O type. AW High VI possibly better than plain AW.

However each application has its own unique performance needs and using a better performace grade may not give any better results.

Your query is more appropriate for productions oils, like Metal working or cutting oils. Take the case of "Gun drilling" or Trepanning operations. In the 90's Castrol India offered Ilocut 334, Ilocut 3341 and Ilocut 534. Each one different from the other in both price and performance. MICO India preferred to use Ilocut 534 and they observed that with the the Sandvik "Cormonut" drill or for that matter similiar, Widia drill, Mico India was able to get more number of pieces drilled with Ilocut 534, than with Ilocut 334 or Ilocut 3341.

Trust this answers your query.
